a [Q 2O I9 is COMPACT WATER PIPE BACKGROUND OF THE INVENTION Thisinvention relates generally to a smoking device, and more particularlyto an improved liquid filtered smoking device which is portable, readilyadaptable to cleaning, and particularly useful in connection with thesmoking of rare and expensive tobaccos.

Prior art water pipes usually suffer from the disadvantages that theyconsist of one or more flexible hoses which have a great tendency to getclogged up as a result of the smoke which passes therethrough. Suchprior art water pipes are large, bulky and quite difficult to maintainand clean, and they must often be completely discarded after extensiveuse. Additionally, such pipes are unsanitary, complicated in theirconstruction, and extremely inefficient when it is attempted to use suchpipes for the smoking of rare and expensive tobaccos.

It is, therefore, a primary object of this invention to provide a newand improved smoking device. which avoids all of the above-mentioneddisadvantages.

An additional object of this invention is to provide a smoking devicewhich is easy to clean and for which replacement parts can be readilyhad.

Still another object of this invention is to provide a smoking devicewhich is sturdy and rugged in its construction.

Yet an additional object of this invention is to provide a smokingdevice which is uniquely well suited for the purpose of smoking rare andexpensive tobaccos.

Another object of this invention is to provide a smoking device that isportable and readily adaptable to efficient shipment in bulk.

An additional object is to provide a water pipe that will not spillwater when tilted or caused to fall on its side.

Still another object is to provide a water pipe which can be used inconjunction with various sizes of liquid compartments to change thevolume of filtering fluid at the users option.

Yet another object of this invention is to provide a smoking devicehaving a unique reversible bowl which is capable of retaining a smalleror a larger amount of smoking tobacco at the users option.

SUMMARY OF THE INVENTION Briefly, in accordance with this invention, acompact water pipe is provided which comprises a first hollow elongatedtube having top and bottom open ends, closure means secured across thebottom end to permit fluid to be retained in the tube, a second hollowelongated tube having top and bottom ends, said bottom end beinginserted into the first tube and the top end extending outwardlytherefrom, and a reversible smok' ing bowl connected to the top end ofthe second tube for retaining smoking tobacco and permitting smoke topass into the tube. A top closure cap is provided for the open end ofthe first tube to prevent fluid from spilling in the event the tube istilted or caused to fall on its side. A plurality of holes within thetop closure cap enables the user to draw smoke therethrough withoutremoving the cap.

As the smoking tobacco is burned, smoke passes through an orifice in thereversible smoking bowl and into the second tube, and continues downinto the fluid.

The user of the device draws air at the open end of the first tube,thereby creating a partial vacuum and caus' ing the smoke to filterthrough the fluid and be drawn up into the first tube, whereby it isinhaled by the smoker. The water pipe is adapted to fit into aconventional fish bowl in order to increase the volume of filteringfluid, as will be hereinafter explained in greater detail.

DESCRIPTION OF THE EMBODIMENT The specific nature of the invention aswell as other objects and advantages thereof will clearly be apparentfrom the following description and. the associated drawings.

FIG. 1 illustrates a cross-sectional view of a smoking devicesubstantially in accordance with this invention.

FIG. 2 shows a cross-sectional view of the reversible bowl for use inaccordance with this invention.

Referring more particularly to FIG. 1, thewater pipe of the presentinvention is illustrated generally by the numeral 10. A first hollowcylindrical tube 15 is provided with top open end 17 and bottom open end16 which is provided with closure cap 12 secured thereacross to permitfluid 13 to be retained within the tube. A second hollow elongated tube18, having a bottom open end 19 and a top open end 29, is inserteddiagonally into the first tube and secured therein.

Liquid 13, which may be any suitable filtering liquid such as water,wine, or other liquid as desired, is retained within the tubes and comesup to the liquid level line 14. The location of liquid level line 14 isat the users option and need not be precisely specified. It isimportant, however, that bottom closure cap 12 provide a secure andliquid tight'seal across open end 16 of tube 15 in order to retainliquid therein. This can be achieved by use of a conventional. plasticor rubber cap which is designed to fit snugly across the bottom of thetube as shown.

Smoking bowl 20 is adapted to fit directly over open end 29 of tube 18,and smoking compartment 24 of bowl 20 is designed to receive the smokingtobaccos.

Located across the top open end 17 of tube 15 is an additional closurecap 11 having a plurality of holes 27 therethrough. Cap 11 is alsodesigned to fit snugly across the open end of the tube: so as to retainfluid therein. The holes 27 are designed to be in the center of closurecap 11 such that in the event that the device 10 is tilted or caused tofall on its side, the liquid 13 would not come up to a sufficiently highlevel so as to emerge through holes 27.

In operation, the smoking tobacco is placed within compartment 24 ofsmoking bowl 20 and is lit by the user. Simultaneously, the user placeshis mouth over holes 27 of open end 17 (or he may remove cap 11 andplace his mouth directly over openend 17) and draws thereupon so as tocreate a partial vacuum in region 26 of tube 15. Smoke from the burningtobacco will be drawn through orifice 25 and will continue down throughtube 18 and into liquid 13 by virtue of open end 19 of tube 18. Thesmoke then filters through the liquid 13 and continues upward intocylindrical tube 15, passing through liquid level line 14 and continuingupward until it reaches the users mouth.

If a greater amount of filtering fluid is desired, bottom closure cap 12can be removed and the entire device 10 may be inserted directly intothe open end of a conventional fish bowl. A suitable air tight andrubber like retaining piece may be provided to maintain the devicerigidly within the fish bowl. In this way, the volume of the fish bowlwould permit a substantial increase in the amount of retained liquid,which would in turn provide more filtering to the smoke. Naturally,different size fish bowls would provide a variety of filtering media.

This new pipe arrangement is particularly efficient in that all of thesmoke created by burning the tobacco in compartment 24 ultimately endsup in region 26 of tube and is entirely, at the option of the user,drawn into the users lungs. Accordingly, little or no smoke is wastedinto the atmosphere as is the case with prior art inefficient pipes.

Referring now to FIG. 2, the details of reversible bowl will bedescribed. Reversible bowl 20 comprises essentially of a first smokingcompartment 24 having an inside diameter D and a second smokingcompartment 28 also having the same inside diameter D. The two smokingcompartments are connected by an orifice 25 having a sufficient diameterto permit smoke to pass therethrough while being capable of retainingthe smoking tobaccos. Orifice 25 is large enough to permit ashes to fallthrough, thus clearing an air passage which tends to mellow the smoke.The bowl, which is preferably made of aluminum or other suitablematerial, is designed to fit snugly over the open end of cylindricalmember 18, as illustrated in FIG. 1. It should be apparent that eithercompartment 24 or 28 can be made to slip over opening 29 of member 18,and that in eitherevent, the appropriate remaining compartment becomes asmoking compartment. Thus, a single unitary device is capable ofproviding the user with two separate smoking bowls each having the samediameter but each having a different length (D or D such that adifferent amount of smoking tobacco may be utilized with the samesmoking pipe. Another use of this reversible bowl is disclosed in mycopending application, Ser. No. 357,186, filed May 4, 1973.

Referring again to FIG. 1, it will be apparent that the smoking deviceis quite simple to maintain and to keep clean. Thus tube 18 can easilybe removed from tube 15 and smoking bowl 20 can easily be removed fromthe tip of tube 18. In this way, all component parts of the water pipecan be placed inside of the large tube 15 during storage or during bulkshipment, thereby enabling the device to be efficiently stored and/orshipped.

For use in operation, cylindrical member 18 is maintained at an acuteangle with respect to the vertical orientation of cylindrical member 15.This arrangement is, however, merely exemplary, and it will beunderstood that the functions and orientations of the cylindricalmembers need not be precisely as shown in the attached drawing. Thus,appropriate interchanges would be well within the ability of personshaving ordinary skill in the art. The cylindrical members 15 and 18 arepreferably made of transparent material such as glass or suitabletransparent plastics so as to enable the user to determine readily thelevel of liquid and smoke contained therein. As previously noted, theentire device can be inserted into a conventional bowl, such as a fishbowl, so as to significantly increase the volume of filtering liquid 13.This arrangement is fully illustrated in applicants co-pendingapplication. Again, the device is designed so as to virtually eliminatethe possibility of liquid spillage. Closure caps 11 and 12 fit snuglyover tube 15 so as to prevent any liquid spillage. Holes 27 are designedto be in the center portion of closure cap 11 such that the liquid levelline 14, in the event of a tilting of device 10, would still not risesufficiently high so as to pass through these holes. Indeed, accidentalwater spillage is virtually eliminated.

Other appropriate and suitable modifications can be made to thestructure of this device without departing from the spirit and scope ofthe inventive concept claimed herein. Thus, reversible smoking bowl 20,as well as closure caps 11 and 12, can be adapted to fit over theappropriate open ends in any of a number of well known ways such as theuse of bayonet mounts, conventional screw threads and simply slip ontechniques. The same principle applies with respect to the insertion ofcylindrical member 18 within member 15. During storage or shipment, tube18 as well as reversible how] 20 are removable from the angular positionshown in FIG. 1 and will easily fit within the larger tube 15. t

It should be apparent from the foregoing that a new and improved smokingdevice has been provided which is uniquely suitable for smoking rare andexpensive tobaccos and which is portable as well as readily adaptable tocleaning and efficient maintenance.
